I ordered mine from Eckler's on 15-Feb. They didn't have it in stock, so I cancelled the order because Corvette Mods said they could get it in 7-10 days. so I ordered it on 23-Feb. The sales guy lied because I didn't get it in 7-10 days and cancelled the order on 21 Mar. I placed the order with Eckler's on 21-Mar and picked it up at their showroom on 22-Mar. I am guessing I cancelled the order on 15-Feb but they still had it ordered from Borgeson and placed it in inventory. I think Eckler's will order from Borgeson and pay for the part to get it to you faster. Eckler's part number is 25-244030 if you want to order it through them.
If you don't already have it make sure you order the Ridetech steering box reinforcement. This bracket will prevent the flex of the steering box. It was $81.99 through Eckler's, Part# 25-374526. Hopefully you have a small block because I put a 427 with Hooker header side pipes and had to beat two tubes to get the gearbox and bracket installed. If you do go with the Ridetech steering box reinforcement make sure you use your original carriage bolts or buy new ones. I would not use the hex head bolts that come with the bracket. See attached pictures.
I am assuming since you are wanting to change to a Borgeson gearbox you are going to do away with the steering assist cylinder and valve.
If you don't already know you will need a different rag joint, the Borgeson steering upgrade relay rod adapter and Borgeson power steering hose kit.
Also I wouldn't use the brass inserts that come with the gearbox. I ordered Part# CLP-605SOL from Summit Racing. This is the steering box and power steering pump fittings get both fittings for $16.00. I did my 68 Camaro and used the inserts. Doing research I saw a video from someone that used these Summit fittings instead of the brass inserts. I ordered two sets because I going to remove the inserts from the Camaro gearbox and go with these fittings. They will seal a lot easier than the inserts.
Any other questions let me know because I replaced my whole front suspension. Everything except the upper and lower A-arms.
I purchased my Borgeson kit off fleabay for around $650, which was a STEAL!
Theres a current listing on eBay item number 164025733417. Shows it’s the last kit in stock.
Part number for the c3 is 999032.
Like was mentioned in an earlier post, don’t forget the Ride Tech bracket.
Best of luck!
Less air flow, but I had no choice. I wasn't going to switch to exhaust manifolds. I will still have plenty of power.
Whenever someone asks about this on here, someone mentions that a performance engine TV program did a dyno test where they progressively beat the ever living crap out of a set of headers until they were basically mangled, with no real power loss.
From the stock manifolds (2" outlet) to any other short header, not much. Be it 2 1/2" outlet rams horns, 1981-style shorty "headers", or McJacks-style shorty headers, there is a small gain, but enough to justify the cost, unless you really need to keep a stock-ish appearance, and have something that bolts to the stock exhaust (like the stock 69 sidepipe headers, for example).
The big advantage is from long-tube headers. And if the Engine Masters data is to be believed, it is the tube length that makes the biggest difference, not a few dimples in the tubes.
